PLANTER.

nppneation'mea september 13, 192e. Isensi No. esame.

citizen of the United.States, residing at Judson, inthe county of Morton and State of yNorth-Dakota, have,y invented new and usefulImprovements in Planters, of which the following is a specifica-tion. y

This'invention relates to agricultural `im:- pl'emcnts, particularly to planters7 and has for its object the provision of anoveldevicedesignedY primarily' for planting corn, the device including a tripfor` dropping the seedactnated by a Wheel instead of by the usual check Wire employed inconnection@ with :ordinary jcorn planters.

An Air'nportant object isfthe provision of a device of this character'wliich may be used as a drill fornplanting other seeds; instead of merely corn, the utility being manifest.

'Anv additional object isthe provision of a device. of this'character which will be simple and linexpensive in manufacture, eflicient and durable in service and a general 'improveinen-t inthe art. y

Vith the above-and other :objects and advantages invievv the invention consists inthe details of construction to be` hereinafter more fully described and claimed and illustrated in the accompanying drawings i in which planter and showing 'the trip mechanism,

'Figure 2 is a longitudinal 'sectionshoW- ing the action of the trip, o l

`Figure 3 isa cross sectional 'vievv taken on the` line 3--3 of fFigure 6, I

vFigure- 4 is a section onthe line 4-4 of Figure l,

Figure 5 is aperspectiveview ofthe valve plate and itsguide,

Figure 6 is a detail perspective view' of the dropping shoe.

Referring more particularly to the drawings the numeral l5 designates the side bars of the frame, which side bars are connected at, their forward ends by a cross bar 16. Journaled transversely of the side bars is an axle 18 Which has its -ends carrying ground engaging Wheels 19 which are relatively Wide as shown so as to have a large surface bearing upon the ground.

Depending from the forward corners of the frame are supports 43 upon the upper ends of Which are secured guides 44 above Which are mounted hoppers 45 having open movable strip 49 guided asf-shotvnfandgpro- 4vided with an upturn'ed end 50jconstijtu'ting ahandle. Each V"suppert isy formedivith a passage 51v ivhich l'eadstcVA the Lb'otto'm thereof and which communicates with 'an M r,521m hthe guide 44.

'Extendif; ltera'ily' from thesidesfo'f the y arranged lthat Athey converge downwardly and forwardly to provide afsp'ace between them wthrough which'the grain ffalls'from the passage 51 into *the furrow` cut 'bythe disks.' Secured to the rearside ofthe supports 43 are blocks 55 upon Which are mounted depending Scrapers 56 which engage the disks 54 yand -which 'are forzthe vpurpose of removing any dirt or mudivhich may cake thereon so that tliedisks `Will al- ;vvays be kept clean and "'s'harp.

'l The seed dropping means fco'nsists of a rock shafty 57 Wlnchis Joiunaled'transversely of Vtheframe bars 15 and Whichcarlries atrip arm 58 having' a downwardly'inclined end as clearly sl'ioWn in'FigureG of the ydrawings disposed in the path oft-travel of pins 59 which project'froinfthe inside face of one of the ground-engagingwvheels 19. Secured upon the ends o'f 'thej rock shaftr? are-rocker arms 60 each of`-avliich is 'provided .at its lofvver Lend vvi'th -a-fbrlr 6l vWithin which is pivo'ted j a "bar" 62 'ivhicli extendstransversely ofthe :passage y51 in the associated support 43. 'y 'On thetop of each rocker arm 60 is a fork 63 Within Which'is pivoted a link 64 which is in turn pivotally connected With the forked end 65 of a plate 66 which is slidable through the adjacent guide 44 between the opening 48 in the bottom plate of the hopper and the opening 52 which communicates with the passage 51. A coil spring 6'? is connected with one rocker arm 60 and With the adjacent support 48 for normally holding the plates 66 in such position as to prevent passage of grain out of the hoppers. On one support 43 is an abutment 66 engaged by a stop arm 69 on the adjacent member or rocker arm for limiting the movement of the parts in one direction.

Disposed against the outside of the right wheel is a marker formed as a bar 74 held against the spokes by U-bolts or clamps and having pointed ends 76 which extend beyond the periphery of the wheel for penetrating engagement with the ground.

In the operation, the device is pulled over the field which has been previously plowed and disked or otherwise harrowed to prepare it for seeding. The hoppers 45 are of course filled with the corn kernels or other grain to be planted. The normal position of the parts is such that the plates 66 cut off communication between the hoppers and the passages 51. When the device is pulled along, at every rotation of the ground engaging wheels7 the pins 59 will engage the trip arm 58 and swing the same downwardly, which will result in rocking the rock shaft 57 which carries the members 60. The upper ends of the members 60 will be moved rearwardly away from the hoppers and against the resistance of the spring 67. When this occurs whatever seed kernels are within the holes 7 3 in the plates 66 will be dragged to a point above the openings 52 in the guides and will drop through these openings into the passages 5l through which they will pass and fall onto the ground in the furrows made by the disks 54. As soon as the pin 59 passes out of engagement with the arm .58 the springs 67 will operate to return the members 60 and rock shaft 57 to original position, the plates 66 returning 'to normal position closing the openings 52 so that no more seed will fall until the trip arm is again operated at the next rotation of the ground wheel. After the seed is dropped into the furrow the ground wheels will operate to close the ground together on to the seeds so that they will be covered and ready for the action of nature to cause sprouting thereof.

The size of the wheels of the machine is such that the marking points 7 6 will-make an impression in the ground exactly three feet and six inches apart. As the wheel turns these points or lugs come in contact with the ground at the side of each hill planted so that this mark will constitute a guide which will enable the operator to set the machine at the end of each row, so that the hills in the successive rows will be exactly in line when drilling corn.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and consequently inexpensive device for planting corn or other grain which has the great advantage ef eliminating the use of the usual check wire and which will therefore be more convenient to use as avoiding a great deal of annonince and difficulty. Owing to the simplicity of the construction and the fewness of the parts itis apparent that there is very little to get out of order and that the device should have a long life and satisfaetorilv perform all the functions for which it is intended.

lWhile I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention I claim:

In a second drop valve device for a planter seed chute having upper and lower valves pivoted respectively to the upper and lower ends of a rock arm journalled intermediate its ends in a planter frame to rock about a horizontal iris, a stop device for limiting the movement of the rocker arm in one direction comprising hammer shaped stop arm carried by the rocker arm and extending forwardly therefrom at right angles thereto at a point just below the connect-ion of the rocker arm with the upper valve, said stop arm having a flat contacting surface for engaging a complementary stop arm carried by the upper part of the seed chute and integral therewith.

In testimony whereof I aflix my signature.

ADOLPH SLAVICK.
